As far as I can see watcher library does not allow selective filtering of specific files. It's either recursive or not for the given root path. We would probably have to roll out our own implementation. @4e6 any thoughts?

[4e6]

We can try to update the library first https://mvnrepository.com/artifact/io.methvin/directory-watcher

Just a moment...

Hubert Plociniczak reports a new STANDUP for yesterday (2023-10-31):

Progress: Address remaining comments for custom log levels PR #8162. Investigating possible solutions to #7695, limited by the rather closed API of the directory-watcher library. It should be finished by 2023-11-01.

Next Day: Next day I will be working on the #7695 task. Prepare a potential workaround for the bug.
